Mandriva Linux Security Update Advisory
_______________________________________________________________________
Package name: smb4k
Advisory ID: MDKSA-2005:157
Date: September 6th, 2005
Affected versions: 10.1, 10.2
______________________________________________________________________
Problem Description:
A severe security issue has been discovered in Smb4K. By linking a
simple text file FILE to /tmp/smb4k.tmp or /tmp/sudoers, an attacker
could get access to the full contents of the /etc/super.tab or
/etc/sudoers file, respectively, because Smb4K didn't check for the
existance of these files before writing any contents. When using super,
the attack also resulted in /etc/super.tab being a symlink to FILE.
Affected are all versions of the 0.4, 0.5, and 0.6 series of Smb4K.
The updated packages have been patched to correct this problem.
